Vegetables can absorb heavy metals from contaminated irrigation water

Certain vegetables take up heavy metals from contaminated water used for irrigation, a new study finds. The researchers grew vegetables in greenhouses similar to field conditions in Greece and found that concentrations of nickel and chromium increased in potatoes and onions, but not in carrots, when irrigated with water containing contaminant levels similar to those found in industrial wastewater.

Coast around Alang-Sosiya shipbreaking yard in India ‘strongly polluted’ with heavy metals

The Alang-Sosiya shipbreaking yard in India is highly polluted with heavy metals, a study concludes. The researchers studied heavy metal contamination in sediments taken from the intertidal zone of the shipbreaking yard and compared them to a control site. The area was found to be ‘strongly polluted’ with copper, cobalt, manganese, lead and zinc.

Pollutants at India’s biggest ship recycling yard, including heavy metals and petroleum hydrocarbons, quantified

A study of the pollution caused by ship scrapping in Alang, India, shows significantly higher levels of heavy metal and petroleum hydrocarbons in sediment and seawater, compared to a control site. The researchers also found reduced populations of zooplankton — a critical food source for marine biota — and increased numbers of pathogenic bacteria.

Reduced heavy metals and nitrogen in mosses reflect falling air pollution across Europe

Deposition of heavy metals and nitrogen is falling across Europe, a new study suggests. The researchers used the levels of these pollutants in mosses as indicators of how deposition has changed from 1990 to 2010. These reductions are likely to be the result of effective air pollution policies, they say.

New nanomaterials could purify water contaminated with heavy metals

Researchers have analysed the ability of two organic nanomaterials to remove the heavy metal chromium from water. In the laboratory, the nanomaterials successfully took up around 95% of the chromium. Further work is needed to confirm the feasibility of using these nanomaterials to purify water in real-world conditions.

Of moss and men: Using moss as a bioindicator of toxic heavy metals at the city scale

Air quality is a critical issue affecting the health of billions of people worldwide, yet often little is known about what is in the air we breathe. To reduce air pollution’s health impacts, pollution sources must first be reliably identified. Otherwise, it is impossible to design and effectively enforce environmental standards. However, urban networks of air quality monitors are often too widely spaced to identify the sources of air pollutants, especially for pollutants that do not disperse far from their sources. Developing high-resolution pollution maps with data from these widely spaced monitors is problematic.

Composite foliage Si fertilizer for lowering contents of heavy metals and nitrate in vegetable, and preparation method thereof

The present invention is related to the field of environmental protection, more specifically, to a foliage silicon fertilizer and a method for production of the fertilizer, which is a molybdenum-silica compound sol used for reducing heavy metal and nitrates in vegetables. The fertilizer, which is a molybdenum-silica compound sol, comprises 10-25 wt % silica, 0.05-5.5 wt % molybdenum ions. More preferably, the fertilize, which is a rare earth-molybdenum-silica compound sol, comprises 10-25 wt % silica, 0.05-5.5 wt % molybdenum ions and 0.1-7.5 wt % rare earth ions. By the combination of silica with molybdenum in the present invention, it is effective for preventing the absorption/accumulation of nitrates in vegetables. In addition, by the further combination with rare earth element, the prevention ability of the fertilizer from absorbing heavy metal and nitrates into vegetables is even enhanced. With a preparation method with normal pressure and relatively, low temperature, that is, with mild condition, simple process and high operability, large scale production of the present invention may be readily executed.
