In the title compound, [Cd(C10H8O4)(H2O)2)]n, the CdII cation is coordinated in a distorted trigonal–prismatic fashion. 3-(4-Carb­oxy­phen­yl)propionate (cpp) ligands connect the CdII cations into zigzag [Cd(cpp)(H2O)2)]n coordination polymer chains, which are oriented parallel to [101]. The chains aggregate into supra­molecular layers oriented parallel to (10overline{1}) by means of O—H⋯O hydrogen bonding between bound water mol­ecules and ligating cpp carboxyl­ate O atoms. The layers stack in an ABAB pattern along [100] via other O—H⋯O hydrogen-bonding mechanisms also involving the bound water mol­ecules. The crystal studied was an inversion twin.

The asymmetric unit of the title inorganic–organic salt, poly[di(μ2-2-hy­droxy­propano­ato)cadmium], [Cd(C3H5O3)2]n or [Cd(Hlac)2]n (H2lac = 2-hy­droxy­propanoic acid), comprises of a cadmium cation and two 2-hy­droxy­propano­ate anions. The cadmium cation exhibits a distorted penta­gonal–bipyramidal coordination environment defined by the hy­droxy and carbonyl O atoms of the 2-hy­droxy­propano­ate anions. The coordination mode leads to the formation of layers extending parallel to (010). O—H⋯O hydrogen bonding between the hy­droxy and carbonyl groups stabilizes the structure packing.

In the title compound, [Cd4Cl8(C6H16N2)4], the Cd2+ cations and Cl− anions form M4Cl8 clusters with six of the Cl− ions bridging Cd2+ cations and two being pendant. Each Cd2+ cation has distorted octa­hedral coordination completed by four Cl− ions and two N atoms of the asymmetrical bidentate amino ligand. The cluster consists of pairs of face-sharing hexa­hedra linked by a shared edge.

In the title compound, [Cd2(C6H9N3O2)2Cl6], the coordination polyhedra around the CdII cations are distorted trigonal bipyramids. Two of the chloride ions (one axial and one equatorial) are bridging to the other metal atom, leading to a Cd⋯Cd separation of 3.9162 (4) Å. The O atom of the l-histidinium cation lies in an axial site. In the crystal, numerous N—H⋯Cl, N—H⋯O, C—H⋯O and C—H⋯Cl hydrogen bonds link the mol­ecules into a three-dimensional network. Theoretical calculations and spectroscopic data are available as supporting information.

In each of the two independent mol­ecules in the asymmetric unit of the title compound, [CdI2(C18H14N4O)], the N,O,N'-tridentate N'-[(E)-(phen­yl)(pyridin-2-yl-κN)methyl­idene]pyridine-2-carbohydrazide ligand and two iodide anions form an I2N2O penta­coordination sphere, with a distorted square-pyramidal geometry, with an I atom in the apical position. Both mol­ecules feature an intra­molecular N—H⋯N hydrogen bond. In the crystal, weak aromatic π–π stacking inter­actions [centroid–centroid separation = 3.830 (2) Å] link the mol­ecules into dimers.

A cadmium germanium arsenide compound, Cd3Ge2As4, was synthesized using a double-containment fused quartz ampoule method within a rocking furnace and a melt-quench technique. The crystal structure was determined from single-crystal X-ray diffraction (SC-XRD), scanning and transmission electron microscopies (i.e. SEM, STEM, and TEM), and selected area diffraction (SAD) and confirmed with electron backscatter diffraction (EBSD). The chemistry was verified with electron energy loss spectroscopy (EELS).

In the title compound, [Cd(NO3)2(C13H11N3)2], the CdII atom lies on a twofold rotation axis and is coordinated by four N atoms and two O atoms, provided by two bidentate 2-(1H-benzimidazol-2-yl)aniline ligands, and two nitrato O atoms, forming a distorted octa­hedral geometry [range of bond angles around the Cd atom = 73.82 (2)–106.95 (8)°]. In the ligand, the dihedral angle between the aniline ring and the benzimidazole ring system is 30.43 (7)°. The discrete complex mol­ecule is stabilized by an intra­molecular N—H⋯O hydrogen bond. In the crystal, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules, forming a three-dimensional network.

The new title one-dimensional CdII coordination polymer, [Cd(C10H10N2)2(μ1,3-N3)2]n, has been synthesized and structurally characterized by single-crystal X-ray diffraction. The asymmetric unit consists of a CdII ion, one azide and one 1-benzyl­imidazole (bzi) ligand. The CdII ion is located on an inversion centre and is surrounded in a distorted octa­hedral coordination sphere by six N atoms from four symmetry-related azide ligands and two symmetry-related bzi ligands. The CdII ions are linked by double azide bridging ligands within a μ1,3-N3 end-to-end (EE) coordination mode, leading to a one-dimensional linear structure extending parallel to [100]. The supra­molecular framework is stabilized by the presence of weak C—H⋯N inter­actions, π–π stacking [centroid-to-centroid distance of 3.832 (2) Å] and C—H⋯π inter­actions between neighbouring chains.

The whole mol­ecule of the cadmium(II) complex, di­iodido­{N,N',N'',N'''-[pyrazine-2,3,5,6-tetra­yltetra­kis­(methyl­ene)]tetra­kis­(N-methyl­aniline)-κ3N2,N1,N6}cadmium(II), [CdI2(C36H40N6)], (I), of the ligand N,N',N'',N'''-[pyrazine-2,3,5,6-tetra­yltetra­kis­(methyl­ene)]tetra­kis­(N-methyl­aniline) (L), is generated by a twofold rotation symmetry; the twofold axis bis­ects the cadmium atom and the nitro­gen atoms of the pyrazine ring. The ligand coordinates in a mono-tridentate manner and the cadmium atom has a fivefold CdN3I2 coordination environment with a distorted shape. In the zinc(II) complex, dichlorido{N,N',N'',N'''-[pyrazine-2,3,5,6-tetra­yltetra­kis­(methyl­ene)]tetra­kis­(N-methyl­aniline)-κ3N2,N1,N6}zinc(II) di­chloro­methane 0.6-solvate, [ZnCl2(C36H40N6)]·0.6CH2Cl2, (II), ligand L also coordinates in a mono-tridentate manner and the zinc atom has a fivefold ZnN3Cl2 coordination environment with a distorted shape. It crystallized as a partial di­chloro­methane solvate. In the crystal of I, the complex mol­ecules are linked by weak C—H⋯I contacts, forming ribbons propagating along [100]. In the crystal of II, the complex mol­ecules are linked by a series of C—H⋯π inter­actions, forming layers lying parallel to the (1overline{1}1) plane. In the crystals of both compounds there are metal–halide⋯π(pyrazine) contacts present. The Hirshfeld analyses confirm the importance of the C—H⋯halide contacts in the crystal packing of both compounds.

The Trump administration has finalized its rollback of a major Obama-era climate policy, weakening auto emissions standards in a move it says will mean cheaper cars for consumers.

"By making newer, safer, and cleaner vehicles more accessible for American families, more lives will be saved and more jobs will be created," U.S. Secretary of Transportation Elaine L. Chao said in a statement.

But consumer watchdog organizations, environmental groups and even the Environmental Protection Agency's own scientific advisory board have raised concerns about that rationale, saying the weakened standards will lead to dirtier air and cost consumers at the gas pump long-term.

Environmental Protection Agency administrator Andrew Wheeler called the new rule a move to "correct" greenhouse gas emissions standards that were costly for automakers to comply with.

"Our final rule...strikes the right regulatory balance that protects our environment, and sets reasonable targets for the auto industry," Wheeler said in a statement.

The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule will toughen carbon dioxide emissions standards by 1.5% a year through model year 2026, compared to about 5% a year under the Obama policy.

The Trump administration originally proposed freezing the standards altogether without any increase. It modified the rule after push back from not only environmental groups but also some automakers, who worried they will be out of step in a global marketplace increasingly geared toward lower emission cars and trucks.

Still, critics say the new rule will lead to nearly a billion additional metric tons of climate warming CO2 in the atmosphere, and that consumers will end up losing money by buying about 80 billion more gallons of gas.

"This rule will lead to dirtier air at a time when our country is working around the clock to respond to a respiratory pandemic whose effects may be exacerbated by air pollution," said U.S. Senator Tom Carper (D-Del.) in a statement. He's the top Democrat on the Senate Environment and Public Works Committee.

The Trump administration asserts the new rule will save lives because Americans will buy newer, safer vehicles. But Carper points out that its own analysis finds there would be even more premature deaths from increased air pollution.

For that reason and others, the new standards are sure to face legal challenges. In fact, even the Trump administration's own science advisers have said "there are significant weaknesses in the scientific analysis of the proposed rule."

"The rollback of the vehicle emissions standards is based on analysis that is shoddy even by the shockingly unprofessional standards of Trump-era deregulation," said Richard Revesz of the Institute for Policy Integrity and Dean Emeritus at New York University School of Law.

California and other states are also likely to file suit against the rule. They've asserted their long-standing right to set their own, stricter emissions standards, something the Trump administration has also challenged.

A worst case scenario for automakers would be different standards in different states. The new policy may ultimately be decided by the U.S. Supreme Court, but the uncertainty waiting for that would exact its own toll on an industry that must plan years ahead.

Thomas Pyle, President of the American Energy Alliance, welcomed the new standards. In a statement, he said the Obama-era mandate was "impossible to achieve without dramatically altering the automobile market or making the cost of vehicles out of reach for most American families. This new... rule will make cars more affordable for consumers at a time when they need it most."

The Trump administration has been pushing ahead with a number of environmental rollbacks, aiming to finalize them well ahead of November's election. That would make it harder for a Democratic president, if one were elected, to reverse them again.

Sustainable consumption and production (SCP) programmes are frameworks to systemically develop sustainability. New research has analysed three national SCP programmes in the UK, Sweden and Finland and concluded that, rather than provide a strong roadmap for sustainability, they tend to be a toolbox of good but scattered initiatives.

Integrated environmental modelling (IEM) is an organised approach to streamlining the movement of scientific information from its research sources to its application in problem solving, according to a study that envisions a global-scale IEM community. The researchers present a roadmap for the future of IEM, describing issues that could be addressed to develop its potential even further, such as how best to integrate diverse stakeholder perspectives and appropriate guidelines for ‘problem statements’.

Administrative sanctions against environmental crime, such as fines, are generally easier and cheaper to implement than criminal punishment methods, such as prison sentences. This study explored enforcement methods for environmental crime in four Western European areas: Flanders (Belgium), Germany, the Netherlands and the UK. Based on their findings, the authors say it is most cost-effective — and may increase deterrence — to use both forms of enforcement.

Exposure to polluted soil can affect human health, but the risk may vary depending on the soil type. A recent study has shown that the differing amounts of cadmium and lead that can be dissolved in the human digestive system can be predicted for contaminated agricultural, urban and woody habitat soils using a model. Its authors suggest this is a useful method for assessing the risks of contaminated land.

The health impacts of consuming food that has been grown using cadmium-contaminated fertilisers are an increasing concern. New Danish research has estimated that the annual monetary cost of these impacts is €15.53 per km2 of agricultural land treated with mineral fertilisers. This cost rises to €37.04 per km2 if pig manure is used.
