Science of The Total Environment, 1991
Abstract The effect of 64 priority pollutants on the growth of Lactuca sativa in nutrient solution was determined, and quantitative structure-activity relationships (QSARs) were established relating EC 50 values with octanol/water partition coefficients (log K ow ) of the test chemicals.

Soil Science, 1989
We studied zinc phytotoxicity with lettuce seedlings in solution culture. Zinc absorption in lettuce (Lactuca sativa L. cv. Climax) consisted of two distinct uptake phases; a slow uptake phase below 5 μM and a rapid uptake phase above 5 μM of solution Zn.

Phytotoxicity of ionic liquids
Chemosphere, 2019Ionic liquids (ILs) have been one of the most interesting chemical entities over the last two decades and have been investigated by numerous scientists all over the world. However, during IL research, it has been shown that these compounds present toxicity to both terrestrial and aquatic plants, among others.

Municipal Sludge-induced Phytotoxicity
Alternatives to Laboratory Animals, 2005Municipal sludge (MS), containing various types of environmental pollutants, can exert phytotoxic effects in plants. Seed germination, chlorophyll content, plant weight, root and shoot growth, and metal levels, were measured as endpoints to assess the phytotoxic effects of leachates of MS from Lucknow city in three plants, Triticum aestivum, Brassica ...

Phytotoxic lignans ofLeucophyllum frutescens
Natural Toxins, 1999Bioassay-guided fractionation of the hexane:ethyl acetate (1:1) extract of the leaves of Leucophyllum frutescens (Berl.) I.M.Johnst (Scrophulariaceae) led to the isolation of its phytotoxic constituents diayangambin (1), epiyangambin (2), diasesartemin (3) and epiashantin (4). Phytotoxicity was demonstrated as inhibition of seed germination of Agrostis

Phytotoxic compounds from endophytic fungi
Applied Microbiology and Biotechnology, 2022Weeds represent one of the most challenging biotic factors for the agricultural sector, responsible for causing significant losses in important agricultural crops. Traditional herbicides have managed to keep weeds at bay, but overuse has resulted in negative environmental and toxicological impacts, including the increase of herbicide-resistant species.

Surfactant-Induced Phytotoxicity
Weed Technology, 1994The leaves of tall morningglory, giant duckweed, and common purslane were treated with nine surfactants at a concentration of 0.1% and examined after 24 hr using cryo-scanning electron microscopy for phytotoxicity as evidenced by tissue damage and epicuticular wax morphology changes.

Archives of Neurology & Psychiatry, 1934
Many eminent students of the schizophrenic psychosis have postulated for it a toxic genesis. Many statements have appeared in the literature that have been interpreted as tending to substantiate this theory, while an equally formidable number has been presented tending to refute it. Because of these conflicting opinions, tests for this hypothetic toxin
