Seizurogenic chemicals include a variety of toxic agents, including chemical warfare agents, toxic industrial chemicals, and natural toxins. Chemical weapons such as sarin and VX, and pesticides such as parathion and carbaryl cause hyperstimulation of cholinergic receptors and an increase in excitatory neurotransmission. Glutamatergic hyperstimulation can occur after exposure to excitatory amin...

In occupational medicine, measurements of levels within the urine of toxic chemicals, or their metabolites, are used to indicate the level of exposure of workers to chemicals. In a worker’s body the kidney is the main organ taking care of the excretion of unwanted/toxic chemicals and the recovery of useful ones, via three mechanisms: filtration, reabsorption and secretion. We model these proces...

CONTEXT Industrial waste (which is composed of various toxic chemicals), changes to the disposal process, and addition of chemicals should all be monitored and controlled carefully in the industrial waste industry to reduce the health hazard to workers. CASE PRESENTATION Five workers in an industrial waste plant developed acute toxic hepatitis, one of whom died after 3 months due to fulminant...

Annex 12 addresses definitions, general principles, programs, monitoring, early warning system, human health, research, and reporting. This annex embraces the philosophy of zero discharge and the goal of virtual elimination, and the Parties have achieved considerable success in controlling direct, point source discharges of toxic chemicals to the lakes. The Commission finds, however, that there...

Iost toxic diseases can be divided into those which result from consumption or exposure to toxic chemicals or poisonous plants. They can be prevented by limiting access to these chemicals and plants. Copper Toxicity, Causes— (a) excessive copper ingestion, (b) absence of sufficient molybdenum in diet, (c) injury to liver tissue from plant alkaloids enabling the liver to store excess copper, (d)...

This review summarizes the findings from a retrospective study of 17,390 forensic autopsy cases of medicolegal investigations in Taiwan during the 1999-2008 period. Among this total, 1,874 cases involved illicit drugs and 750 involved household toxic chemicals. Rarely seen toxic substances, such as cyanide, corrosive poisons, ether, etc., were found in 6.4%percent; of homicide poisoning cases. ...

Influences of phenol, α-naphtol and β-naphtol, which are toxic chemicals, on citric acid biosynthesis and biomass in the artificial culture setting of Aspergillus niger using batch fermenter are examined in the most favorable fermentation conditions, and a model is proposed. Addition of certain concentrations of phenol, α-naphtol and β-naphtol to the culture reduces the citric acid production. ...

Pesticides are a group of chemicals made for the purpose of killing or otherwise deterring “pest” species. The word pesticide may refer to insecticides, herbicides, fungicides, or other pest control formulations. Pesticides are inherently toxic and often associated with adverse health effects in non-target organisms.1 Organochlorine pesticides are a large class of multipurpose chlorinated hydro...
