Hence these parameters have been studied by comparing the use of distilled water and commercially available 2%
para-dichlorobenzene ear drops in a similar way.
This product, called Fuji Lavender Moth Tablets, contained
para-dichlorobenzenepopulation for nine organic chemicals: bisphenol A (BPA), five phthalates [butyl benzyl phthalate (BBzP), di(2-ethylhexyl) phthalate (DEHP), diethyl phthalate (DEP), di(isobutyl) phthalate (DiBP), and di(n-butyl) phthalate (DnBP)],
para-dichlorobenzene (DCB), methyl paraben (MP), and triclosan.
Roots from rooted hardwood cuttings were collected, pre-treated with a saturated solution of
para-dichlorobenzene at 16[degrees]C for 3 hours, fixed at 3:1 (ethanol and acetic acid, respectively) solution and stored at -20[degrees]C until the cytological analyses.
By substituting walnut shells in one process, for example, it cut use of
para-dichlorobenzene by some 80 percent.
The headline of a July news release from NIEHS inappropriately stated that the chemical 1,4 dichlorobenzene, which the agency said may impair lung function, is found "in many air fresheners." In an interview with the Raleigh, NC, News & Observer and a media advisory issued immediately thereafter, CSPA noted that the chemical, which is more commonly known as
para-dichlorobenzene (PDCB), may still be found in some urinal blocks, mothballs and hanging deodorizers.
The compound,
para-dichlorobenzene, is used to make mothballs, urinal deodorizers, and air-freshening blocks for household use.
Small amounts of
para-dichlorobenzene were used to protect the collections from infestation by dermestids and other harmful insects.
Para-dichlorobenzene (PDCB) is sometimes added to the blocks.
Stored frames should also be protected by fumigating them with
para-dichlorobenzene crystals.
Simple improvements (some of which are already mandated by state law) include removing
para-dichlorobenzene cake toilet deodorizers; installing "walk-off" mats at all major entries, which keeps schools cleaner and helps prevent pollutants being tracked indoors; ensuring air intakes are clear and open on the outside; prohibiting bus and car idling near the building; and phasing in the use of nontoxic cleaning products and pest control methods.
