Recent reports concerning the lethal effects of solar ultraviolet-B (UV-B) (290-320 nm) radiation on amphibians suggest that this stressor has the potential to impact some amphibian populations. In this study embryos and larvae of three anuran specie

In recent years, there has been an increased use of the measurement of sex steroid hormone levels in the blood of animals exposed to chemicals as an indicator of reproductive impairment or an alteration in endocrine function. Although levels of hormo

An assessment of the toxicity of phthalate esters to freshwater benthos. 2. Sediment exposures

Autor: D J, Call, D A, Cox, D L, Geiger, K I, Genisot, T P, Markee, L T, Brooke, C N, Polkinghorne, F A, VandeVenter, J W, Gorsuch, K A, Robillard, T F, Parkerton, M C, Reiley, G T, Ankley, D R, Mount

Publikováno v: Environmental toxicology and chemistry. 20(8)

Seven phthalate esters were evaluated for their 10-d toxicity to the freshwater invertebrates Hyalella azteca and Chironomus tentans in sediment. The esters were diethyl phthalate (DEP), di-n-butyl phthalate (DBP), di-n-hexyl phthalate (DHP), di-(2-e

Publikováno v: Environmental toxicology and chemistry. 20(8)

Tests were performed with the freshwater invertebrates Hyalella azteca, Chironomus tentans, and Lumbriculus variegatus to determine the acute toxicity of six phthalate esters, including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl ph

Factors affecting reproduction and the importance of adult size on reproductive output of the midge Chironomus tentans

Autor: P K, Sibley, G T, Ankley, D A, Benoit

Publikováno v: Environmental toxicology and chemistry. 20(6)

We conducted two separate tests to evaluate the influence of several factors that could affect estimation and interpretation of effects on reproductive output of Chironomus tentans in sediment toxicity tests. Specifically, the influence of adult size

Description and evaluation of a short-term reproduction test with the fathead minnow (Pimephales promelas)

Autor: G T, Ankley, K M, Jensen, M D, Kahl, J J, Korte, E A, Makynen

Publikováno v: Environmental toxicology and chemistry. 20(6)

Due to the time and expense associated with full life-cycle testing, most current toxicity tests with fish do not explicitly consider reproductive output as an endpoint but, rather, focus on early life-stage survival and development. However, some cl

Publikováno v: Environmental toxicology and chemistry. 20(5)

We evaluated the effectiveness of Ambersorb, a carbonaceous resin, in reducing bioavailability of polycyclic aromatic hydrocarbons (PAHs) in contaminated sediments collected from the field. In laboratory studies, sediment pore-water concentrations of
