Toxicity and uptake of nitroguanidine in plants
Bulletin of Environmental Contamination and Toxicology, 1990During the manufacture of the munition nitroguanidine (NQ), wastewater is contaminated by NQ and related by-products. Land application of the NQ-contaminated wastewater was initiated after discussions with the Kansas Department of Health and the Environment and the US Environmental Protection Agency.

Plant–herbivore interactions mediated by plant toxicity [PDF]
Theoretical Population Biology, 2008 We explore the impact of plant toxicity on the dynamics of a plant-herbivore interaction, such as that of a mammalian browser and its plant forage species, by studying a mathematical model that includes a toxin-determined functional response. In this functional response, the traditional Holling Type 2 response is modified to include the negative effect

The Journal of Agricultural Science, 1912
The writer has pointed out the influence that some agricultural plants have on others when grown in close proximity to them. It was demonstrated (inter alia) that a row of Sesamum indicum (gingelly), when sown at a distance of two feet from a row of Sorghum vulgare (great millet), will not mature, the plants dying after reaching a height of a few ...

Agriculture and Environment, 1982
The toxicity of ammonia was evaluated and an estimate is given of (mass) concentration for no adverse effect: 75 μg/m3 for a yearly average, 600 μg/m3 for 24 h and 10 000 μg/m3 for 1 h. Ammonia can cause various types of injury, including necrosis, growth reduction, growth stimulation and increased frost sensitivity.

This review looks critically at the relevance of lead (Pb2+) toxicity and proposed mechanisms of Pb2+ -induced stress in algae and higher plants. As a basis, the current main sources of Pb2+ contamination in the environment are presented, which include agriculture, industry, and road traffic. Further, bioavailability of lead is discussed as a basis for

Plant responses to metal toxicity
Comptes Rendus de l'Académie des Sciences - Series III - Sciences de la Vie, 1999Metal toxicity for living organisms involves oxidative and/or genotoxic mechanisms. Plant protection against metal toxicity occurs, at least in part, through control of root metal uptake and of long distance metal transport. Inside cells, proteins such as ferritins and metallothioneins, and glutathion-derived peptides named phytochelatins, participate ...

Toxic plants: a chemist’s perspective [PDF]
, 2010 Chemistry has long been an integral part of toxicology, as the two fields originated in much the same way: the investigation of plants with interesting properties. In this chapter I review the role that chemistry has played in understanding toxic and medicinal plants. After some introductory remarks, three broad areas are addressed: the role of natural
