Toxicities of Polycyclic Aromatic Hydrocarbons for Aquatic Animals.
Masato Honda,Nobuo Suzuki +1 more
TL;DR: PAHs have a toxicity for aquatic animals, indicating that the prevention of aquatic PAH pollution should be emphasized, and the correlation between PAHs and microplastics is described.
Journal ArticleDOI
Effects of metal contaminants on the development of the common Antarctic sea urchin Sterechinus neumayeri and comparisons of sensitivity with tropical and temperate echinoids
TL;DR: Embryos and larvae of the sea urchin were exposed to the metals copper, cadmium, zinc and lead, and the effects of each metal on development to hatched blastulae after 6 to 8 d, and to 2-arm plutei after 20 to 23 d were monitored.
Journal ArticleDOI
Effects of heavy metals on sea urchin embryo development. 1. Tracing the cause by the effects.
Naomasa Kobayashi,Hideo Okamura +1 more
TL;DR: The toxicity of the polluted waters originating from a disused lead mine was evaluated using both sea urchin bioassays and heavy metal analysis to speculate that interactive effects, involving zinc and possibly manganese and nickel, were occurring.
Journal ArticleDOI
The effects of metals on embryo-larval and adult life stages of the sea urchin, Diadema antillarum.
TL;DR: The high sensitivity of both adult and larval D. antillarum to these metals supports the use of this organism as an important biological indicator for metal exposure in marine environments.
Journal ArticleDOI
Effects of heavy metals on sea urchin embryo development. Part 2. Interactive toxic effects of heavy metals in synthetic mine effluents
Naomasa Kobayashi,Hideo Okamura +1 more
TL;DR: Zinc was one of the elements responsible for causing malformations and its effects were intensified by the presence of the other metals, such as manganese, lead, iron, and copper.

Journal ArticleDOI
Fertilization and larval development in sea urchins following exposure of gametes and embryos to cadmium.
TL;DR: The gametes and embryos of three sea urchin species were exposed to cadmium chloride at concentrations ranging from 10−8 M to 10−3 M and skeletal differentiation displayed some severe abnormalities or was suppressed, as a function of Cd2+ level, which was inversely related to salinity and to Ca2+ concentration.
Journal ArticleDOI
Comparative sensitivity of various developmental stages of sea urchins to some chemicals
TL;DR: It seems that sperm activity is the most sensitive, and that fertilization and gastrulation are more sensitive than first cleavage, blastulation and pluteus formation.

Effects of sodium azide on sea urchin embryos and gametes

TL;DR: The consequences of sperm pretreatment on offspring quality failed to show any significant SA-induced changes on larval malformations or mortality, while confirming the previously reported pH-induced increase of developmental defects in the offspring of acid-exposed sperm.
