Arsenic-based drugs are permitted in poultry production. Inorganic arsenic (iAs) causes cancer and maybe other adverse health outcomes. The contribution of chicken consumption to iAs intake, however, is unknown. The objective of the study is to characterize arsenic species profile in chicken meat and estimate bladder and lung cancer risk associated with consuming chicken produced with arsenic-based drugs.

Prospective studies that evaluate the influence of arsenic methylation capacity on cardiovascular disease (CVD) risk are lacking. The objective of the study is to evaluate the association of arsenic exposure from drinking water and arsenic methylation capacity with CVD risk..

In many parts of the world, livestock production is undergoing a process of rapid intensification. The health implications of this development are uncertain. Intensification creates cheaper products, allowing more people to access animal-based foods. However, some practices associated with intensification may contribute to zoonotic disease emergence and spread, for example the sustained use of antibiotics, concentration of animals in confined units, and long distance and frequent movement of livestock.

Ambient air pollution may have neurotoxic effects in children. Data examining associations between traffic-related air pollution and attention domains remain sparse. The researchers examined associations between black carbon (BC), a marker of traffic particles, and attention measures ascertained at age 7-14 years among 174 children in a Boston-based birth cohort.
