AND INTRODUCTION In the Western United States poisonous plants are estimated to cost the animal industry more than 200 million dollars annually. The majority of these losses are attributed to livestock grazing on rangelands. Little has been done to determine the costs of livestock poisoned by contaminated feeds which are probably more frequent and costly. Grazing livestock generally avoid eatin...

Pyrethroid insecticides induce an excito-repellent effect that reduces contact between humans and mosquitoes. Insecticide use is expected to lower the risk of pathogen transmission, particularly when impregnated on long-lasting treated bednets. When applied at low doses, pyrethroids have a toxic effect, however the development of pyrethroid resistance in several mosquito species may jeopardize ...

Phytoremediation of creosote-contaminated soil was monitored in the presence of Tall fescue, Kentucky blue grass, or Wild rye. For all three grass species, plant growth promoting rhizobacteria (PGPR) were evaluated for plant growth promotion and protection of plants from contaminant toxicity. A number of parameters were monitored including plant tissue water content, root growth, plant chloroph...

INTRODUCTION A medical visit for plant ingestion is rare in the pediatric emergency services but may involve a high toxicity. The botanical toxicology training of health staff is often very limited, and it can be difficult to make a diagnosis or decide on the appropriate treatment. OBJECTIVE To study the epidemiological and clinical characteristics of poisoning due to plant ingestion in order...

Complex toxic effects of Cd2+, Zn2+, and acid rain on growth of kidney bean (Phaseolus vulgaris L) were studied in a pot experiment by measurement of fresh weights of the plants, determination of surperoxide dismutase (SOD), peroxidase (POD), and lipid peroxidation (MDA) in the plant organs, and observation of injury symptoms. The experimental results demonstrated that all treatments of Cd2+, Z...

Background: A pot experiment was conducted to determine the toxic effects of some heavy metals on the plant growth and seed yield of maize (Zea mays L.). Materials and Metheds: Heavy metals Mn, Pb, Cd, Cr and Co individually and in combinations were added as chloride salts in solutions to the pots before sowing. The test plants for were harvested after 80 days of germination and evaluated f...

Fly ash from Mae Moh power plant in Lampang province, northern Thailand (unit 6, 8, 10 and 11) was investigated to find out the heavy metals (As, Cd, Hg, Pb Zn) content of fly ash. Every metal except mercury is at higher level than background soil. The average arsenic two times soil unit 11 contains largest amount (148.5 mg kg-1). Mercury dumping site not detectable. Sludge, end product wastewa...

The accumulation of toxic metals and metalloids, such as cadmium (Cd), mercury (Hg), or arsenic (As), as a consequence of various anthropogenic activities, poses a serious threat to the environment and human health. The ability of plants to take up mineral nutrients from the soil can be exploited to develop phytoremediation technologies able to alleviate the negative impact of toxic elements in...

Plant salt stress is a condition where excessive salts in soil solution cause inhibition of plant growth or plant death. On a world scale, no toxic substance restricts plant growth more than does salt. Salt stress presents an increasing threat to plant agriculture. Among the various sources of soil salinity, irrigation combined with poor drainage is the most serious, because it represents losse...

Agriculturally grown plants are potentially contaminated with poisonous weeds. Many potentially toxic plants are found in pastures and crops. Consequently, forage crops at harvest or when directly grazed may contain toxic amounts of poisonous plants. Unfortunately, efficient prevention of contamination with certain poisonous plants is not always feasible or practical, and thus, contaminated fee...
