“…They assimilate trace metals from their food and from the ingestion of inorganic particulate material (Phillips, 1977;Struck et al, 1997). In recent years, researchers have focused their attention on the identification of other possible biomonitors for trace metal pollution, such as the gastropod mollusks Monodonta turbinate and Patella cerulea (Conti and Cecchetti, 2003).…”

Mollusks living in seas can accumulate heavy metals, and may serve as excellent passive biomonitors. During a period of 1 year, bioaccumulation of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn was examined in nine kinds of mollusks (Rapana venosa, Neverita didyma, Scapharca subcrenata, Mytilus edulis, Amusium, Crassostrea talienwhanensis, Meretix meretrix, Ruditapes philippinarum, and Mactra veneriformis), which were collected at eight coastal sites along the Chinese Bohai Sea. Metal concentrations were directly determined by inductively coupled plasma mass spectrometer (ICP-MS). Two certified reference materials, dogfish muscle (DORM-2) and mussel (GBW 08571), were used to validate the methods, and the recoveries were within 83.72 -112.30% of the certified values. Bioaccumulation of metals varied strongly among sampling sites and species. Statistical analysis (one-way ANOVA) indicated that different species examined showed different bioaccumulation of metals, and perhaps they could be used as potential biomonitors to investigate the contamination levels of heavy metals. Principal component analysis (PCA) and correlation analysis were used to study the relationships between these heavy metals. The results showed that, in nine mollusks' tissues, there are significant correlations between these elements in adjacent main group or subgroup in periodic table of elements. D

“…The BCF value that greater than 1 ppm indicated heavy metal accumulator, however, it will be a good bioaccumulator when the BCF was greater than 1,000 ppm (Conti and Cecchetti, 2003). Based on the Conti and Cecchetti (2003) criteria, result of this research shown that P. cruentum was only in the category of bioaccumulator, rather than good bioaccumulator similar to the result of Sekabira et al (2011).…”

“…Based on the Conti and Cecchetti (2003) criteria, result of this research shown that P. cruentum was only in the category of bioaccumulator, rather than good bioaccumulator similar to the result of Sekabira et al (2011). However, it does not mean that P. cruentum do not good bioaccumulator, since Conti and Cecchetti (2003) developed BCF for fish, therefore it was difficult to gain the criteria of good bioaccumulator for microalgae due to the microscopic size that was very difficult to reach BCF of more than 1,000 ppm. However, the short of accumulation time was the advantages of P. cruentum as a good organism to remediate heavy metal pollution.…”

The red microalgae Porphyridium cruentum (S.F. Gray) Nägeli usually was used as feeds, a pigment for food and cosmetic, and antiviral activity that might be became industrial interest. Similar to another microalgae, P. cruentum has an ability to remediate heavy metals pollution, however research on it still limited. This research was conducted in order to find out the accumulation of Pb, Cd, Cr, and Cu on the P. cruentum. A laboratory experiment were developed with different concentrations. Based on this research, P. cruentum with the treatment of 1 mg/L had reduced higher Cu, Pb, Cd, and Cr concentrations rather than 3 and 5 mg/L concentrations, respectively. This was also similar to the BCF, that in day 8 in order of Cu > Cr > Cd > Pb, respectively; however, in day 15 was Cu > Pb > Cd > Cr. The length of treatment influenced BCF value. P. cruentum was good for bioremediation of heavy metal pollution, with the advantage of the short of accumulation time.

We examined the removal of hazardous heavy metals (Cd, Cr, and Pb) from laver Pyropia sp. using citric, hydrochloric, and nitric acids. Under the same conditions, the quality of the laver samples was also evaluated using the variation in absorbance and major mineral levels. The heavy metals that accumulated in raw laver samples after 3 days in seawater included Pb (117.79 μg/g), Cr (33.53 μg/g), and Cd (10.54 μg/g) in descending order. The rate of heavy metal removal from laver was higher at lower pH for all acids used. However, its color changed unsatisfactorily at pH 2.0. After 10 min in seawater at pH 2.5, the heavy metals in laver were eliminated in the order Cd (68.7-81.6%), Pb (57.7-67.0%), and Cr (31.9-49.4%) using the three acids. The differences in heavy metal removal among acid types were not significant. The laver quality was not affected after 20 min at the pH range of 2.5-4.0. The maximum removal of heavy metals was from laver soaked for 10 min in seawater at pH 2.5 using the organic acid, citric acid.
