Its biological features and soil climatic conditions limit the cultivation of peanuts in Ukraine. A prerequisite for obtaining high stable peanut yields is sowing with high-quality seeds characterized by excellent yield properties.

The purpose of this research was to identify the variables that increase concern about the health, environmental contamination, and economic consequences of toxic substances in the environment. A mail survey was sent to a New York State sample, and a 66% response was obtained. Seven indices were developed from specific concerns about toxic substances in the environment including, among others, ...

ger's (R-CA) signature on Sep-tember 29, California became the first U.S. state to approve two laws that will move its regulatory scheme toward a comprehensive chemicals policy. The legislation is intended to improve public and environmental health protection and encourage green chemistry-the design of chemical products and processes that reduce or eliminate the use or generation of hazardous s...

Methods 29 children (17 boys and 12 girls), aged from 14 days to 17 years old with different CHD underwent content analysis of following toxic substances: Al, Cd, Pb, Hg, Be, Ba, Tl, Bi, As, Ni, Sb , Sn, Sr, Ti, W, Zr, Ag, Li, B, Co, Si, V in intraoperative (23) and autopsy (6) biopsy tissue samples of heart (n=37) and great vessels (n=18) by atomic emission and absorption spectrometry methods ...

Despite early warnings of lead toxicity, until recently this metal was added to a variety of consumer and industrial products. Today, thousands of children in the United States, and probably tens of thousands more worldwide, are suffering the consequences of exposure to lead. The lead story looms as major public policy failure that will eventually cost billions of dollars to remedy. Little is k...

This paper gives a review of established and emerging technologies for the treatment of wastes and soils contaminated by Persistent Toxic Substances which include the Persistent Organic Pollutants. The technologies are classified as biological, physico-chemical, and thermal treatments, describing main unit operations and comparing technical, social and environmental limitations, including some ...

Methods for predicting organic solvents, chromic acid, mineral oil, styrene, and sulphuric acid emissions in painting, metal degreasing, wood preservation, chromium electroplating, turning, grinding, making glass fortified polyester laminates and lead batteries charging, injection moulding of polystyrene plastics, and making polyurethane foam processes are described. Experimentally introduced e...

Migratory grazing of zooplankton between non-toxic phytoplankton (NTP) and toxic phytoplankton (TPP) is a realistic phenomena unexplored so far. The present article is a first step in this direction. A mathematical model of NTP–TPPzooplankton with constant and variable zooplankton migration is proposed and analyzed. The asymptotic dynamics of the model system around the biologically feasible eq...

BACKGROUND/AIM Acrylic-based resins are intensively used in dentistry practice as restorative or denture-base materials. The purpose of this study was to analyze the surface structure of denture base resins and the amount of released potentially toxic substances (PTS) immediately upon polymerization and incubation in different types of artificial saliva. METHODS Storage of acrylic samples in ...
