Importance of sperm density in assessing the toxicity of metals to the fertilization of broadcast spawners.

Ecotoxicol Environ Saf 2019 Feb 14;172:547-555. Epub 2019 Feb 14.

Faculty of Engineering Sciences, University College London, GPO Box 2471, Adelaide SA 5001, Australia.

Many marine invertebrates reproduce through broadcast spawning, where sperm and eggs are released into the water column and are vulnerable to toxicants present in the environment. The potential impacts of toxicants on spawning success are often assessed through laboratory-based fertilization tests. In most cases, these tests assess toxicant impacts at a single, pre-defined sperm density, based on a sperm:egg ratio that ensures high fertilization success (≥70-80%) in a filtered seawater control.

A New Model Describing Copper Dose⁻Toxicity to Tomato and Bok Choy Growth in a Wide Range of Soils.

Int J Environ Res Public Health 2019 Jan 18;16(2). Epub 2019 Jan 18.

Institute of Agricultural Resources and Regional Planning, Chinese Academy of Agricultural Sciences, Beijing 100081, China.

Phytotoxicity thresholds for heavy metals are derived from dose⁻response curves, which show the relationships between exposure dose and toxicity response. However, the results of tests or observations are commonly based on total heavy metal concentration, not the exposure dose that causes phytotoxicity; additionally, the phytotoxicity response differs with plant species. In the present study, the ethylenediaminetetraacetic acid (EDTA)-extractable copper (Cu) concentration was determined in order to evaluate Cu extractability. Read More

A two-photon fluorescent probe for colorimetric and ratiometric monitoring of mercury in live cells and tissues.

Chem Commun (Camb) 2019 Feb;55(12):1766-1769

Department of Chemistry and Nano Science, Ewha Womans University, Seoul, 120-750, Korea.

Owing to the extreme toxicity of mercury, methods for its selective and sensitive sensing in solutions, and in live cells and tissues are in great demand. In this study, we developed a naphthalimide-based diphenylphosphinothioyl group-containing fluorescent and colorimetric probe that selectively detects mercury (Hg2+). Upon addition of mercury (Hg2+) to a solution of the probe, both a colorimetric change from colorless to yellow and a fluorescence change from blue to green (under a 365 nm hand-held UV lamp) occur, both of which can be observed using the "naked-eye".
