“…A recent study showed that despite BPA being undetectable in surface water (less than 0.18 µg L –1 ), levels of BPA in fish ranged from 1 to 6 µg kg –1 dry weight 69. BPA was also detected in supermarket seafood from Singapore, including prawn, crab, blood cockle, white clam, squid and fish, with concentrations between 13.3 and 213.1 µg kg –1 wet weight 70. BPA in surface water also can contaminate drinking water, as lower levels of BPA (up to 1.3 µg L –1 ) have been reported in potable tap water 71…”

Low‐Dose Bisphenol A Exposure: A Seemingly Instigating Carcinogenic Effect on Breast Cancer

Breast cancer is the fifth most common cause of cancer death in the world and the second most common fatal cancer in women. Epidemiological studies and clinical data have indicated that hormones, including estrogen, progesterone, and prolactin, play important roles in the initiation and progression of breast cancer. Bisphenol A (BPA) is one of the most commonly used and thoroughly studied endocrine disruptors. It can be released from consumer products and deposited in the environment, thus creating potential for human exposure through oral, inhaled, and dermal routes. Some recent reviews have summarized the known mechanisms of endocrine disruptions by BPA in human diseases, including obesity, reproductive disorders, and birth defects. However, large knowledge gaps still exist on the roles BPA may play in cancer initiation and development. Evidence from animal and in vitro studies has suggested an association between increased incidence of breast cancer and BPA exposure at doses below the safe reference doses that are the most environmentally relevant. Most current studies have paid little attention to the cancer‐promoting properties of BPA at low doses. In this review, recent findings on the carcinogenic effects of low‐dose BPA on breast cancer and discussed possible biologic mechanisms are summarized.

“…Some fish species from Adriatic Sea, Italy, have NP levels from 12 to 1,431 ng/g w.w. and OP levels of 0.3-4.7 ng/g w.w. (Ferrera et al 2005). Basheer et al (2004) presented concentrations of NP about 60.5 ng/g w.w. and OP about 31.4 ng/g w.w. in fish in Singapore. Fish in the UK were found to contain up to 0.8 ng/g w.w. of NP in the muscle tissue (Ying et al 2002), whereas geometrical mean of NP in snails and oysters was calculated in range of 380-1,560 ng/g and 92-1,080 ng/g d.w., respectively.…”

Alkylphenols and their precursors, alkylphenol etoxylates, are a group of manmade chemicals used mainly as surfactants in domestic and industrial applications worldwide. It has been well established that they have endocrine disruption activity, hepatotoxic, genotoxic and other negative effects on animal and human health. In spite of the effort to reduce their use, they persist in the environment not only in industrial but also in remote regions, and were detected in the variety of natural matrices including air, water, soil as well as food products, and human blood and urine worldwide. This article summarizes their occurrence, fate in natural conditions, and toxicity including mode of action. A subject of our concern was the aquatic environment as the most important reservoir and target of their deleterious impact.

“…EDCs are mainly discharged into aquatic environment through domestic and industrial wastewater, either directly or after treated, and the coastal waters are consequently their final recipients (Ying et al 2002;Basheer et al 2004;Beck et al 2005). Contamination of EDCs in the coastal area is not only more severe but also more sensitive to environmental factors than that in the deep ocean due to the short distance from pollution sources and the limited diffusion ability (Zoller 2006).…”

Occurrence and distribution of three typical endocrine-disrupting chemicals (EDCs), nonylphenol mixture (NPs), bisphenol A (BPA), and 17α-ethynilestradiol (EE2), were investigated in the seawater, suspended solid, and sediment around the coastline of Shenzhen city. Field surveys were conducted in both dry season and rainy season to access the influence of rainfall and basic water quality parameters on the distribution of target EDCs. In the seawater, NPs, BPA, and EE2 ranged from 31 to 1,777 ng/l, from 11 to 777 ng/l, and from 10 to 269 ng/l, respectively. In the suspended solid, NPs, BPA, and EE2 were in the range from 3 to 289 ng/l, from 1 to 75 ng/l, and from 1 to 29 ng/l, respectively. In the sediment, NPs, BPA, and EE2 varied from 9 to 355 ng/g dry weight (dw), from 3 to 156 ng/g dw, and from 7 to 144 ng/g dw, respectively. With the increasing rainfall, the concentrations of target EDCs decreased in seawater and sediment and increased in suspended solid at all the sampling locations. Among the six measured basic water quality parameters, the volatile suspended solid value was positively related with the partition property of target EDCs between suspended solid and seawater. Based on the results of principal component analysis, dissolved organic carbon, total nitrogen, and total phosphorous had close relationships with the distribution of target EDCs in the seawater. Temperature and dissolved oxygen had little relationship with the distribution of target EDCs in the coastal area.
