Trichechus manatus ) in Puerto Rico is mortality due to human activities. We assessed 90 cases of manatee strandings in Puerto Rico based on
historical data and a coordinated carcass salvage effort from 1990 through 1995. We determined patterns of mortality, including
type of event, condition of carcasses, spatial and temporal distribution, gender, size/age class, and the cause of death.
The spatial distribution of stranding events was not uniform, with the north, northeast, and south coasts having the highest
numbers. Six clusters representing the highest incidence included the areas of Fajardo and Ceiba, Bahía de Jobos, Toa Baja,
Guayanilla, Cabo Rojo, and Rio Grande to Luquillo. The number of reported cases has increased at an average rate of 9.6%/yr
since 1990. The seasonality of stranding events showed a bimodal pattern, from February through April and in August and September.
Most identified causes of death were due to human interaction, especially captures and watercraft collisions. Natural causes
usually involved dependent calves. From 1990 through 1995, most deaths were attributed to watercraft collisions. A reduction
in anthropogenic mortality of this endangered species can be accomplished only through education and a proactive management
and conservation plan that includes law enforcement, mortality assessment, scientific research, rescue and rehabilitation,
and inter- and intraagency cooperation. 相似文献

The first reports that it is possible to emit dioxins from the heat and power generation sector are from the beginning of the 1980s. Detailed research proved that the emission of dioxins might occur during combustion of hard coal, brown coal, and furnace oil as well as coke-oven gas. The emission of dioxins occurs in wood incineration; wood that is clean and understood as biomass; or, in particular, wood waste (polluted). This paper thoroughly discusses the mechanism of dioxin formation in thermal processes, first and foremost in combustion processes. The parameters influencing the quantity of dioxins formed and the dependence of their quantity on the conditions of combustion are highlighted. Furthermore, the methods of reducing dioxin emissions from combustion processes (primary and secondary) are discussed. The most efficacious methods that may find application in the heat and power generation sector are proposed; this is relevant from the point of view of the implementation of the Stockholm Convention resolutions in Poland with regard to persistent organic pollutants. 相似文献
