“…The mean contents of arsenic, Pb, Cd, and Hg in Porphyra sp. that were produced in Korea, Japan and Italy were assessed as harmless (47,48) . However, arsenosugars detected in Porphyra seaweed were metabolised to dimethylarsinic acid in human bodies that is more toxic than arsenosugars (49) .…”

Gim (Porphyra sp.) and miyeok (Undaria pinnatifida) are the seaweeds most consumed by Koreans. We investigated the association between the intake of gim and miyeok and the risk of breast cancer in a case -control study. Cases were 362 women aged 30 -65 years old, who were histologically confirmed to have breast cancer. Controls visiting the same hospital were matched to cases according to their age (SD 2 years) and menopausal status. Food intake was estimated by the quantitative FFQ with 121 items, including gim and miyeok. Conditional logistic regression analysis was used to obtain the OR and corresponding 95 % CI. The average intake and consumption frequency of gim in cases were lower than in controls. The daily intake of gim was inversely associated with the risk of breast cancer (5th v. 1st quintile, OR, 0·48; 95 % CI, 0·27, 0·86; P for trend, 0·026) after adjustment for potential confounders. After stratification analysis was performed according to menopausal status, premenopausal women (5th v. 1st quintile, OR, 0·44; 95 % CI, 0·24, 0·80; P for trend, 0·007) and postmenopausal women (5th v. 1st quintile, OR, 0·32; 95 % CI, 0·13, 0·80; P for trend, 0·06) showed similar inverse associations between gim intake and the risk of breast cancer after an adjustment for potential confounders except dietary factors. Miyeok consumption did not have any significant associations with breast cancer. These results suggest that high intake of gim may decrease the risk of breast cancer.

“…We also observed a positive correlation between Cr and Ni in fish and crayfish from Lake Kariba. Cr and Ni compounds are commonly used as anti-fouling agents in marine paints (Diagomanolin et al 2004) and Pb is often used in gasoline (Muohi et al 2003, Caliceti et al 2002. Given the increase in boat traffic on the lake and the recent increases in Cr and Ni in Lake Kariba sediments we hypothesize that these heavy metals are derived from commercial fishing around, and on, Lake Kariba.…”

Heavy metal accumulation in lake sediments, fish (Oreochromis niloticus and Serranochromis thumbergi) and crayfish (Cherax quadricarinatus) in Lake Itezhi-tezhi and Lake Kariba, AbstractWe measured the level of heavy metal accumulation in lake sediments, herbivorous (Oreochromis niloticus) and carnivorous (Serranochromis thumbergi) fish, and crayfish (Cherax quadricarinatus) from Lake Itezhi-tezhi (ITT) and Lake Kariba. We used atomic absorption spectrophotometry (AAS) to quantify the levels of 7 heavy metals (Cr, Co, Cu, Zn, Cd, Pb, and Ni). The sediment and the herbivorous fish O. niloticus accumulated a very high concentration of Cu in Lake ITT, most likely due to the discharge of Cu waste from a mining area 450 km upstream. The aquatic species we sampled in Lake Kariba had higher concentrations of Cr, Ni, and Pb relative to those in Lake ITT. This is most likely due to anthropogenic activities, such as the use of leaded petrol and anti-fouling agents in marine paints. Interestingly, we observed a negative correlation between the coefficient of condition .

“…Segundo Caliceti et al (2002), algas representam uma importante fonte de economia, principalmente para países banhados pelos oceanos Índico e Pacífico, onde as algas são amplamente retiradas, e também intensamente aplicados na nutrição humana, a nível comparativo à Europa. Apesar disso, é comum na Europa utilizar as algas para extração de iodo e de sódio, pois alguns países como Noruega, Escócia e Islândia passaram por colonização excessiva de determinadas espécies, como a alga Ulva, Enteromorpha, Chaetomorpha e Cladophora.…”

“…Essas algas causaram sérios problemas para a qualidade ambiental e para a economia da população local. Por isso, foram estudados meios de reduzir as superpopulações (CALICETI et al, 2002). De acordo com Vidotti e Rollemberg (2004), algumas espécies de algas possibilitam seu uso na avaliação da qualidade dos sistemas aquáticos, para os quais, inclusive já foi sugerido umbentônica, mudança dos ciclos de nutrientes e ocorrência de crises distróficas.…”
