State regulators have sued FedEx Ground, claiming the company mishandled hazardous chemicals at facilities throughout California during the last 5 years.  

An investigation into a fire four years ago in San Diego prompted a wider inquiry into how FedEx handles restricted chemicals in statewide shipping at all of its facilities.

Regulators claim FedEx didn’t handle thousands of damaged and hazardous packages properly. The state’s complaint claims FedEx would remove damaged packages from shipping and store them for lengthy periods of time in salvage drums, which were moved from hubs to terminals within the company’s network of facilities.  

These packages contained goods ranging from insecticides and acids to old batteries and other flammable and toxic materials – pretty small shipments, less than 65 pounds, but investigators say they’ve found problems with more than 20 tons of goods shipped over a 5-year period.

Each violation alleged in the state’s lawsuit carries a penalty of up to 25-thousand dollars. In a written statement, FedEx spokeswoman Katie Wassmer says the company "complies with all applicable local, state and federal reporting requirements." 

The state-court complaint is the latest legal salvo in a dispute among California and local officials and FedEx.

Earlier this spring, FedEx sued the DTSC and district attorneys from three cities, including Los Angeles, seeking a declaration that federal law pre-empts California's waste handling laws, and that state officials are incorrectly interpreting laws governing FedEx. 

"To preserve our rights as a federally-registered motor carrier, FedEx Ground filed suit in federal court" said Wassmer. "We are confident that a thorough review of the regulatory framework through the judicial process will support our position."

A recent study has described a simple method to screen the toxicity of materials used in consumer products. Using utility meter products as examples, the study found, for example, that stainless steel and polyvinyl chloride (PVC) had high toxicity potentials and suggests less toxic, but equally effective and priced, alternatives that could be used instead.

Research into mercury has identified two genes in bacteria that appear to be required for turning the metal into its most toxic form, methylmercury. The study adds to a growing body of research that helps us to understand the transformations that mercury undergoes in the environment and the microbes involved in these transformations.

Polycyclic aromatic hydrocarbons (PAHs) are a large group of toxic molecules produced by forest fires, industrial processes and the incomplete combustion of fossil fuels. The airborne particles containing these molecules are often washed into watercourses, where they can persist. This study uses long-term monitoring data from the Elbe river, Saxony, Germany, to show how changes in PAH sources affect both the concentrations of these chemicals and the corresponding environmental risks. The researchers suggest that controlling PAHs is the best prevention of harm to aquatic and human health.

Harbour sediments should be tested for their toxic effects on living organisms in addition to being subject to the chemical, physical and biological tests usually conducted to assess water quality, according to recent research from Portugal. This would provide a better environmental assessment of dredged material to help guide port authorities’ decisions on its disposa

Spanish medical and public health researchers have found no clear evidence for increased heavy metal levels in adults living near a recently-built urban solid waste incinerator over two years of operation. Concentrations of lead, chromium and mercury in blood and urine samples taken around the plant were not significantly higher than for populations who lived further away.

Plastic debris is a serious environmental concern, as a physical pollutant as well as a chemical pollutant when it breaks down in the marine environment. A new study has now shown that plastics can also concentrate other pollutants, with significantly higher concentrations of toxic pollutants adhering to soft, rubbery plastics, rather than hard, glassy plastics.

Constructed wetlands can effectively remove veterinary drugs from wastewater, preventing contamination of the environment, research suggests. A recent study has demonstrated that laboratory-scale constructed wetlands were able to remove between 94 and 98% of two commonly used antibiotics from pig farm wastewater.

To assess the impact on ecosystems of chemical contamination in aquatic environments, scientists need to measure not only the concentration of the contaminants, but also the extent to which they can disrupt biological processes at a cellular level in plants and animals and at an ecosystem level. According to a new study, considering these complex inter-relationships in combination will help improve the ecological status of waterways, in line with Water Framework Directive (WFD) commitments.

Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems.

Fin whales (Balaenoptera physalus) are likely being exposed to microplastics and associated toxic additives in the Mediterranean Sea, finds new research. The research analysed levels of microplastics and biological and chemical markers of exposure in whales from the Mediterranean Sea and the comparatively pristine Sea of Cortez, off the coast of Mexico. The results suggest that the vulnerable Mediterranean fin whale may be suffering as a consequence of microplastic pollution.

Considering the impact on soil carbon, biodiversity and ecotoxicity is important when assessing the environmental footprint of dairy products, suggests a new study, which explored the impacts of organic and conventional milk production in three types of system established in Western Europe. The study found that organic milk production had a significantly lower impact on ecotoxicity and biodiversity than conventional milk production, and suggests that including soil carbon changes in the assessment would result in greater reductions in the carbon footprint of organic, rather than conventional, milk — in some cases by up to 18%.

A new study by Swiss researchers has attempted to predict nanomaterial concentrations in the environment. However, the researchers say more data on environmental toxicity are needed before we can make accurate assessments of potential environmental risks from nanomaterials.

Researchers have developed the first biology-based model to predict the sub-lethal effects of chemical mixtures on organisms. Sub-lethal effects do not cause death but can damage processes such as growth and reproduction. The model provided accurate predictions of the sub-lethal impacts of a chemical mixture on water fleas.

A new tool that predicts the effects of complex mixtures in water has shown promising results. It correctly predicted the impacts of toxic mixtures on the model species Daphnia magna, or water fleas, in over 90 per cent of cases.
