Mercury concentrations in two ?great waters?

A survey of size-specific mercury concentrations in game fish from Maryland fresh and estuarine waters.

A survey of size-specific mercury (Hg) concentrations in game fish from a subset of Maryland fresh and estuarine waters was conducted, in which Hg concentrations in 112 fish from seven freshwater impoundments and three tidal and four estuarine locations in Chesapeake Bay and its tributaries were measured. Striped bass (Morone saxatilis) was the most intensively examined species. Of the fish exa...

Data Sets 6 Mercury in Stream Waters

A modified method for the determination of organic mercury in biota [great cormorants (phalacrocorax carbo)] by advanced mercury analyzer

Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...

Geographic, seasonal and ontogenetic variation in cadmium and mercury concentrations in squid (Cephalopoda: Teuthoidea) from UK waters.

Cadmium (Cd) and mercury (Hg) levels were measured in the tissue samples of two loliginid (Alloteuthis sp. and Loligo forbesi) and two ommastrephid (Todarodes sagittatus and Todaropsis eblanae) squid species collected from research cruise and fishery (market) samples in UK waters during 2004-05. Concentrations of Cd were generally higher in the ommastrephids, in all tissues except muscle. Hg co...

Scalp hair mercury concentrations in Pakistan.

The presence of mercury in the environment is widespread and persistent, but the extent of exposure of Pakistanis to mercury is virtually unknown. We collected toenail and scalp hair samples from 158 subjects (83 males and 75 females) residing in Lahore and its suburbs. We also conducted a questionnaire survey and personal interviews to obtain information on demographic factors, lifestyles, and...
