Synthetic polymers are ubiquitous in the modern world but pose a global environmental problem. While plastics such as poly(ethylene terephthalate) (PET) are highly versatile, their resistance to natural degradation presents a serious, growing risk to fauna and flora, particularly in marine environments. Here, we have characterized the 3D structure of a newly discovered enzyme that can digest highly crystalline PET, the primary material used in the manufacture of single-use plastic beverage bottles, in some clothing, and in carpets.

Polycyclic aromatic compounds (PACs), including polycyclic aromatic hydrocarbons (PAHs) and PAH-like compounds are known or probable environmental carcinogens released into the environment as a by-product of incomplete combustion of fossil fuels and other organic materials. Studies have shown that exposure to PACs in the environment can induce both genotoxicity and epigenetic toxicity, but few studies have related PAC exposure to molecular changes in free ranging wildlife.

Melamine and phthalate, mainly di-(2-ethylhexyl) phthalate (DEHP), are ubiquitously present in the general environment. We investigated whether urine melamine levels can modify the relationship between DEHP exposure and markers of early renal damage in children.

A gap in emission inventories of urban volatile organic compound (VOC) sources, which contribute to regional ozone and aerosol burdens, has increased as transportation emissions in the United States and Europe have declined rapidly. A detailed mass balance demonstrates that the use of volatile chemical products (VCPs)—including pesticides, coatings, printing inks, adhesives, cleaning agents, and personal care products—now constitutes half of fossil fuel VOC emissions in industrialized cities.

New report shows how industry managed to sweep harmful effects of pesticides and genetic engineering under the carpet. Eleven out of 12 EU pesticide and GMO risk assessment methods studied were developed or promoted by industry, a new report from Pesticide Action Network (PAN) shows.

Phthalate esters (PAEs) are commonly detected in agricultural soils of China, which can post potential threats to human health. Understanding their sorption to soils is important in assessing their transport and bioavailability in environment. Limited research focuses on the influence of soil organic carbon (SOC) on PAEs adsorption to soils at different depths and increased dissolved organic carbon (DOC) after adsorption.

The recent increase in nanoparticle (P25 TiO2 NPs) usage has led to concerns regarding their potential implications on environment and human health. The food chain is the central pathway for nanoparticle transfer from lower to high trophic level organisms. The current study relies on the investigation of toxicity and trophic transfer potential of TiO2 NPs from marine algae Dunaliella salina to marine crustacean Artemia salina.

The following draft of certain regulations, further to amend the Food Safety and Standards (Contaminants, Toxins and Residues) Regulations, 2011, which the Food Safety and Standards Authority of India, with previous approval of the Central Government, proposes to make in exercise of the powers conferred by clauses (i) and (j) of sub-section (2)

1991 Gulf War (GW) veterans continue to experience debilitating cognitive and mood problems more than two decades following their return from deployment. Suspected causes for these cognitive complaints include additive and/or synergistic effects of the varying combinations of exposures to chemicals in theater, including pesticides and pyridostigmine bromide (PB) pills.

This landmark study published in Lancer finds that toxic air, water, soils and workplaces kill at least 9 millon people and cost trillions of dollars every year. Pollution kills more people in India than anywhere else in the world revealed the study.
