“…The literature suggested that egg sample size varied considerably among different studies, e.g., egg sample sizes of little egret varied between three and five per heronry (Keithmaleesatti et al 2007), 12 eggs from brown boobies at eight colonies from the northern Gulf of California to southern Mexico (Mellink et al 2009), five to 15 eggs per heronry in the study of Henny et al (2003), three to five eggs per colony of great blue herons (Ardea herodias) from Indiana (Baker and Sepu'lveda 2009), three to 14 eggs of little egrets from three breeding heronries of three selected wetlands of Pakistan (Sanpera et al 2003), five to 11 eggs from two cattle egret heronries from south Africa (Bouwman et al 2008), and 20 eggs of cattle egrets from Tai Lake in China (Dong et al 2004). Therefore, in this study, from each heronry, a total of 10 nests were sampled, and one egg from each nest was collected.…”

In this study, residual concentration of organochlorine pesticides (OCPs) in the sediments, prey, and eggs of Bubulcus ibis were measured from three breeding heronries from the Punjab province of Pakistan. Pattern of contamination in eggs followed the order: DDTs>HCHs>heptachlor>aldrin. Overall, pesticide residual concentrations were greater in eggs of cattle egrets collected from heronry on the River Ravi. Among HCHs, γ-HCH was more prevalent in eggs, whereas DDTs followed the order: DDD>DDE>p,p'-DDT>o,p'-DDT. Eggshell thinning was detected which showed negative relationship with residual concentration of DDE. In prey samples, residual concentration of POPs followed the order: DDTs>HCHs>dicofol>heptachlor; however, contamination pattern in sediments followed a slightly different order: DDTs>heptachlor>dicofol>HCHs>dieldrin>aldrin. Concentration of β-HCH was more prevalent in sediments and comparatively greater concentrations of POPs were measured in sediments collected from the River Ravi. Dicofol was found for the very first time in the biological samples from Pakistan, and its concentration was measured as relatively high in eggs from heronry from the River Chenab. Residual concentrations measured in eggs were below the levels that could affect egret populations. Biomagnification of the total OCPs through the food chain was evident in three breeding heronries. The concentration of DDE measured in eggs of the cattle egret suggests the need for monitoring this contaminant in other bird species at different trophic levels.

“…Además, debe mencionarse que en las muestras recogidas en 2006 de huevos de bobos café en el Pacífico mexicano y el Golfo de California, incluidas las islas Marietas, se determinó un nivel bajo de compuestos de metabolitos de organoclorados (diclorodifenildicloroetileno o DDE), lo que se consideró un signo de ecosistema marino costero saludable. Las concentraciones encontradas no están relacionadas con el adelgazamiento de la cáscara del huevo y, por tanto, no ponían en riesgo la eclosión ni el éxito reproductivo (Mellink et al, 2009). Los compuestos organoclorados en las Marietas se relacionaron entonces con los insumos utilizados para el control de mosquitos tanto en Puerto Vallarta como en la Riviera Nayarit.…”

Breeding success of the blue-footed booby, Sula nebouxii, and the brown booby, Sula leucogaster, as an indicator of touristic disturbance in the Islas Marietas, Mexico.-We studied the breeding success of two seabird species, the blue-footed booby, Sula nebouxii, and the brown booby, Sula leucogaster, in relation to touristic disturbance in order to focus conservation management strategies in the protected area of the Marietas Islands in Bahía de Banderas, Mexico. Data were collected throughout the breeding season of 2013 at Isla Larga. We considered three sites under different conditions of simulated disturbance within the colonies: 'medium', visits constrained to a single path; 'high', visits without spatial restrictions, and 'low', no visits. The total numbers of nests, eggs and chicks for each species were recorded weekly at the three sites. On the basis of these data, we determined the viability of eggs (hatching success) and chicks. A generalized linear mixed model (GLIMMIX) showed that breeding success (eggs-to-fledglings rate) had no relationship to the conditions of the area and but was significantly lower in the blue-footed booby. The presence of tourists, as measured in this study, was not the cause of nesting failure. Other, non-evaluated factors likely play a role in limiting the breeding success of the two species of booby studied here.

“…La mayor parte de estos estudios se ubican en las zonas costeras del Pacífico Norte. En este sentido, Mellink et al (2009) detectaron DDE (0.053 µg/g base húmeda) en huevos de bobos cafés (Sula leucogaster) de las islas San Jorge y San Pedro Mártir en Sonora. En la isla Peña Blanca, Colima, se detectaron concentraciones menores a 0.01 µg/g y de acuerdo a los autores, el grosor del cascarón no se vio afectado por las concentraciones de DDE.…”

Palabras Clave: patrón de uso, exposición laboral, ecosistemas, contaminación, agricultura RESUMENEl presente trabajo analiza la investigación que se ha llevado a cabo en México con relación al uso y efecto de los plaguicidas en el ambiente y salud humana. Se revisaron 394 artículos publicados en los últimos 20 años en revistas indizadas o arbitradas. Las publicaciones se agruparon en 7 temas principales: 1) patrón de uso de plaguicidas, 2) efectos en el ambiente; 3) estudios ecotoxicológicos; 4) exposición en población humana; 5) residuos en alimentos; 6) toxicología de plaguicidas (estudios in vitro e in vivo); y 7) bioplaguicidas y biorremediación. El análisis de estas investigaciones indican que actualmente se utilizan Plaguicidas Altamente Peligrosos (PAPs) en las zonas agrícolas del país, su uso histórico y actual se relaciona con efectos negativos en ecosistemas terrestres y costeros, se han reportado efectos en la salud de los trabajadores agrícolas y sus familias, tales como alteraciones hematológicas, hormonales, daños genéticos, alteraciones del comportamiento y daños celulares; los niños constituyen el grupo más vulnerable a la exposición, además se han documentado daños genéticos, reproductivos y neuronales en modelos celulares y en organismos de laboratorio y se reportan residuos en alimentos como leche, hortalizas y granos. Como medidas de mitigación, se documentan procesos de biorremediación de suelos y agua contaminada,
