Human health risk from hexachlorocyclohexane and dichlorodiphenyltrichloroethane pesticides, through consumption of vegetables: estimation of daily intake and hazard quotients

open access: yesJournal of Xenobiotics, 2013
People are encouraged to consume more fresh vegetables due to the high nutritional value and fibre contents in vegetables. At the same time, due to pesticidal residue in vegetables, vegetable consumption is considered as an important route of pesticides ...

Spectral pollution

open access: yesIMA Journal of Numerical Analysis, 2004
We discuss the problems arising when computing eigenvalues of self-adjoint operators which lie in a gap between two parts of the essential spectrum. Spectral pollution, i.e. the apparent existence of eigenvalues in numerical computations, when no such eigenvalues actually exist, is commonplace in problems arising in applied mathematics.

Polluting Politics [PDF]

open access: yesSSRN Electronic Journal, 2015
This paper estimates the causal impact of party affiliation (Republican or Democrat) of U.S. governors on pollution. Using a regression discontinuity design, gubernatorial election data, and air quality data from U.S. Environmental Protection Agency (EPA), we find that pollution is lower under Democratic governors.
