Background Cereal grains are an important for the nutrition of both humans and animals, and contribute to the nutrition cycle in different ways. Chemical contaminants are important to be monitored in food due to their direct effects on human health.

Despite the ban of polychlorinated biphenyls (PCBs) some decades ago, concerns regarding their adverse health effects are continuing, because the workers employed for installation and repair of electrical equipment may be still exposed to PCBs. This study aimed to assess serum PCBs levels in workers in different industries. To do this, we determined the serum concentrations of 9 non-dioxin-like PCBs and 12 dioxin-like PCBs in 147 workers from seven occupational groups and 35 housewives.

Exposure to polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) through food, water, and air occurred during the life, which may change telomere length (TL) in peripheral blood leukocytes. The present study was designed to investigate the association between TL and serum levels of PCBs and OCPs in Tehran male’s population. Whole blood samples were randomly taken from 300 adult males, aged between 25 and 40 years.

To discover natural-product-based pesticides, 7β-oxycarbonylandrographolide derivatives were stereoselectively constructed from a labdane diterpenoid andrographolide.

Seaweed is a source of protein that can help overcome the anticipated challenges of a growing world population and the current challenges for finding alternatives for animal proteins in the Western diet. Thus far, data on the safety of seaweed for feed and food purposes in the Western world are scattered.
