Application Assessment of Passive Sampling to Monitor Polybrominated Diphenyl Ethers in Water Environment as Alternative Sampling Method for Grab Sampling

PASSIVE AIR SAMPLING OF POLYCHLORINATED BIPHENYLS (PCBs) AND POLYBROMINATED DIPHENYL ETHERS (PBDEs) IN BRAZILIAN TROPICAL AND SUBTROPICAL MOUNTAINS

Over the last decade, mountain areas have been receiving more concern about organic pollution due to atmospheric transport and deposition processes. Similar to the polar regions these areas are considered some of the most pristine and remote ecosystems worldwide. However, mountains and associated highlands are subject to the atmospheric deposition of Persistent Toxic Substances (PTS) that inclu...

Application of adaptive sampling in fishery part 1: Adaptive cluster sampling and its strip designs

Abstract:  The precision of conventional sampling designs is not usually satisfactory for estimating parameters of clump and rare populations. Many of fish species live in school and disperse all over a vast area like a sea so that they are rare compare to their habitats. Theory of a class of sampling designs called adaptive sampling designs has rapidly grown during last decade which solv...

Application of adaptive sampling in fishery part 2: Truncated adaptive cluster sampling designs

There are some experiences that researcher come across quite number of time for very large networks in the initial samples such that they cannot finish the sampling procedure. Two solutions have been proposed and used by marine biologists which we discuss in this article: i) Adaptive cluster sampling based on order statistics with a stopping rule, ii) Restricted adaptive cluster sampling. Until...
