“…Due to past use of OC pesticides in agriculture throughout the 1990s, particularly in coffee production, p,p′-DDE has been detected in soil, as well as animal and plant life in coastal waters, with 6.14 ng/g of p,p′-DDE measured in sediments from Portland between October 1991 and December 1992 [13] and 8.3 ng/g in shrimp in Hunts Bay and Kingston Harbor in 1995/1996 [12]. Although most OC compounds were banned for use in Jamaica in 1999 [13], the persistence of these toxicants allows for potential exposure in our unique study population.…”

“…Although most OC compounds were banned for use in Jamaica in 1999 [13], the persistence of these toxicants allows for potential exposure in our unique study population. Compared to Jamaica [30], PCBs and some OC compounds were banned for use much earlier in the U.S. (1979) [31] and in Canada and Europe (1985) [32,33].…”

“…As an island nation, Jamaica has very specific sources of exposure to environmental contaminants, including PCBs and OC pesticides [12,13,14,15]. According to Fernandez et al (2007), PCBs and OC pesticides have been used extensively in the Wider Caribbean Region (WCR), including Jamaica, since the 1930s [14].…”

To date much of the biomonitoring related to exposure to polychlorinated biphenyls (PCBs) and organochlorine (OC) pesticides is from middle to high income countries, including the U.S., Canada and Europe, but such data are lacking for the majority of low to middle income countries. Using data from 64 pregnant mothers who were enrolled in 2011, we aimed to assess the concentrations of the aforementioned toxins in umbilical cord blood serum of 67 Jamaican newborns. For 97 of the 100 PCB congeners and 16 of the 17 OC pesticides, all (100%) concentrations were below their respective limits of detection (LOD). Mean (standard deviation (SD)) lipid-adjusted concentrations in cord blood serum for congeners PCB-153, PCB-180, PCB-206 and total PCB were 14.25 (3.21), 7.16 (1.71), 7.30 (1.74) and 28.15 (6.03) ng/g-lipid, respectively. The means (SD) for the 4,4′-dichlorodiphenyldichloroethylene (DDE)-hexane fraction and total-DDE were 61.61 (70.78) and 61.60 (70.76) ng/g-lipid, respectively. Compared to the U.S. and Canada, the concentrations of these toxins were lower in cord-blood serum of Jamaican newborns. We discuss that these differences could be partly due to differences in dietary patterns in these countries. Despite limitations in our dataset, our results provide information on the investigated toxins in cord blood serum that could serve as a reference for Jamaican newborns.

Effects of shade and bird exclusion on arthropods and leaf damage on coffee farms in Jamaica’s Blue Mountains

et al. 2009

Abstracts The effects of overstory trees and birds on coffee pests are poorly understood. This study documents (a) the effect of bird exclusion on foliagedwelling arthropod abundance and insect-caused leaf damage, and (b) the relationships between vegetation complexity and insect abundance, leaf damage, and prevalence of fungal leaf symptoms on coffee farms in the Blue Mountains of Jamaica, West Indies. Overall arthropod abundance was reduced inside bird-proof exclosures, and this corresponded to reduced insect-caused leaf damage. The reduction in leaf damage increased with greater shade, but fungal leaf symptoms increased with greater shade and proximity to non-coffee habitat patches. There appears to be a trade-off for coffee farmers in our study region: vegetation complexity may attract beneficial insect-eating birds that can reduce insect damage, but it is also associated with the prevalence of fungal leaf symptoms.
