How is it possible that lychee, a deliciously sweet tropical fruit, could induce a fatal hypoglycemic encephalopathy in children? The answer is straightforward: the edible fruit (aril) of lychee or litchi (Litchi sinensis or Litchi chinensis), and other members of the Soapberry family (Sapindaceae), contains unusual amino acids that disrupt gluconeogenesis and β-oxidation of fatty acids.

Aside of immediate impacts, the 2011 Puyehue–Cordón Caulle volcano (PCC) eruption also caused persisting chemical impacts. By 2012, toxicity resulted in overt dental fluorosis in deer, with bone fluoride increasing > 38-fold to 5175 ppm. Sheep, horses and cattle also succumbed to fluorosis. Due to eolian redeposition of tephra, exposure of ruminants continued, bone fluoride reached 10 396 ppm, and by 2014 skeletal fluorosis was found.

Glyphosate is a non-selective, phosphonomethyl amino acid herbicide registered to control weeds in various agricultural and non-agricultural settings. The herbicide acts by inhibiting the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme, which is not present in mammalian systems. Glyphosate was initially registered in 1974.

Assessment of food and environmental safety (AFES) for environmental release of genetically engineered mustard hybird DMH-11 and use of parental events for development of new generation hybirds

Dichlorodiphenyltrichloroethane (DDT) was used extensively to control malaria, typhus, body lice, and bubonic plague worldwide, until countries began restricting its use in the 1970s. However, use of DDT to control vector-borne diseases continues in developing countries. Prenatal DDT exposure is associated with elevated blood pressure in humans.

Diabetes and obesity are major threats to public health in the US and abroad. Understanding the role chemicals in our environment play in the development of these conditions is an emerging issue in environmental health, although identifying and prioritizing chemicals for testing beyond those already implicated in the literature is a challenge.

The aim of the present study is to investigate LC50 values in three seasons of TBTO on L. marginalis. The active substance TBT is highly toxic damaging to non target species. The bivalves have been bioindicators to determine aquatic pollution status. The adverse effect of Tributyltin oxide has been studied on freshwater bivalve mollusk Lamellidens marginalis in summer, monsoon and winter season during June 2014–may 2015. To evaluate the median lethal concentration of TBTO, bioassay was performed in all seasons on fresh water bivalve for 24hr, 48hr, 72hr and 96 hrs.

A method for the determination of 200 pesticides and pesticide metabolites in honeybee samples has been developed and validated. Almost 98% of compounds included in this method are approved to use within European Union, as active substances of plant protection products or veterinary medicinal products used by beekeepers to control mites Varroa destructor in hives. Many significant metabolites, like metabolites of imidacloprid, thiacloprid, fipronil, methiocarb and amitraz, are also possible to detect.

European governments have banned the use of three common neonicotinoid pesticides due to insufficiently identified risks to bees. This policy decision is controversial given the absence of clear consistency between toxicity assessments of those substances in the laboratory and in the field. Although laboratory trials report deleterious effects in honeybees at trace levels, field surveys reveal no decrease in the performance of honeybee colonies in the vicinity of treated fields.
