Ecotoxicology, 2004
Toxicity reduction evaluations (TREs) in the River Esk and Lower Tees Estuary were based on the approach described by USEPA, but adapted to tackle the specific problems of the two sites. A combination of toxicity tracking and toxicity identification evaluation (TIE) was used at both locations to enhance the understanding of source and type of toxicants

Biological Reviews of the Cambridge Philosophical Society, 2000
ABSTRACTSome six or so physiological systems, essential to normal mammalian life, are involved in poisoning; an intoxication that causes severe injury to any one of them could be life threatening. Reversible chemical reactions showing Scatchard‐type binding are exemplified by CO, CN− and cyclodiene neurotoxin insecticide intoxications, and by antigen ...

Current Medicinal Chemistry, 2014
Nowadays more than thousands of different nanoparticles are known, though no well-defined guidelines to evaluate their potential toxicity and to control their exposure are fully provided. The way of entry of nanoparticles together with their specificities such as chemistry, chemical composition, size, shape or morphology, surface charge and area can ...

Toxic Chemicals and Toxic Laws
Science, 1991Recently there was consternation when it was discovered that a program intended to help minorities and the underprivileged in Detroit might have to be canceled. The reason was that some of the land on which new buildings were built was thought to contain toxic chemicals and therefore fell under the provisions of the Comprehensive Environmental Response,

Toxicity and toxic interaction of aniline and pyridine
Bulletin of Environmental Contamination and Toxicology, 1979Chemical characterization of organic contaminants of coal conversion processes such as gasification or liquefaction has revealed them to be a potential source of environmental hazards. The majority of these compounds may be divided into four major classes: (1) phenols, (2) aromatic hydrocarbons, (3) aromatic amines, and (4) sulfur-containing compounds.

Structural Features of Toxic Chemicals for Specific Toxicity
Journal of Chemical Information and Computer Sciences, 1999We have studied the structural features of toxic chemicals from the RTECS database associated with specific toxicity. The frameworks, functional groups, and structure patterns of molecules are taken into account. Potential active frameworks, groups, and structure patterns for specific toxicity are gained by computational chemistry approaches.

Neurologic Clinics, 2005
Effective brain function is dependent on precise and complex interactions among neurotransmitters, hormones, enzymes, and electrolytes. Many of the chemically complex substances with which we come into contact can disrupt this intricately balanced system.

Toxic Nanoparticles and Toxicity
2.İnternational Congress Of Forensic Toxicology, 2016Nowadaysresearch of nanoparticles (NPs) has increasingly found practical use intechnology, and medicine. Nanoparticles (NPs) at the atomic scale of 100 nm orless, has led to numerous use wide applications in electronics, chemicals andbiological medicine.

Lidocaine is recognized as a first line drug for ventricular arrhythmias and has recently been used in acute myocardial infarction as prophylaxis against ventricular fibrillation. A 68-year-old man was erroneously given 2 gm of lidocaine by intravenous push and sustained a cardiac arrest. He was treated supportively and had complete recovery.
