美国环保署为若干类化学物制订进口限制

　　近日，美国环保署（EPA）根据《有毒物质控制法案》为27种物质制定了新的规则，并对其制定了进口限制。该规则要求任何个人在制造、进口这27种物质时至少在90天之间通知EPA。该举动将有助于EPA有机会对这些活动进行评估，如果有必要，可禁止该活动或进行适当限制。

　　这27种被限制进口的物质为：

　　(1)多壁碳纳米管（通用）；

　　(2)单壁碳纳米管（通用）：

　　（3）cobalt lithium manganese nickel oxide;

　　(4)benzoic acid, 4-chloro-2-[(substituted)azo]-strontium salt (1:1)(generic);

　　(5)phosphonium, tetrabutyl-, hydroxide (1:1);

　　(6)aryloxyacrylate (generic);

　　(7)formaldehyde, polymer with 1,3-benzenediol and 1,1′-methylenebis[isocyanatobenzene];

　　(8)4-cyclohexene-1,2-dicarboxylic acid, 1,2-bis(2-oxiranylmethyl) ester;

　　(9)1,3-cyclohexanedimethanamine, N1,N3-bis(2-methylpropylidene)-;

　　(10)amines, di-C11-14-isoalkyl, C13-rich;

　　(11)epoxy terminated, hydrolysed trialkoxysilane and glycidyl ether of phenol-formaldehyde resin (generic);

　　(12)soybean oil, epoxidised, reaction products with diethanolamine;

　　 (13)octadecanoic acid, reaction products with diethylenetriamine and urea, acetates;

　　(14)1,2-ethanediol, reaction products with epichlorohydrin;

　　(15)polyether polyester copolymer phosphate (generic);

　　(16)poly(oxyalkylenediyl),.alpha.-substituted carbomonocycle-.omega.-substituted carbomonocycle (generic);

　　(17)benzenepropanol, .beta.-methyl-;

　　(18)2-propenoic acid, 3-(5,5,6-trimethylbicyclo[2.2.1]hept-2-yl)cyclohexyl ester;

　　(19)branched and linear alcohols (generic);

　　(20)2-propenoic acid, 2-methyl-, C12-15-branched and linear alkyl esters,telomers with alkyl 2-[[(alkylthio)thioxomethyl]thio]-2-alkanoate, aminoalkyl methacrylate and alkyl methacrylate, tert-Bu 2-ethylhexanoperoxoate-initiated (generic);

　　(21)butanamide,N-[substituted phenyl]-[(alkoxynitrophenyl)diazenyl]-3-oxo-(generic);

　　(22)phosphoric acid, polymer with cycloaliphatic diglycidyl ether, alkylethers (generic);

　　(23)phosphoric acid, polymer with cycloaliphatic diglycidyl ether, alkylethers (generic);

　　(24)styrenyl surface treated manganese ferrite (generic);

　　(25)styrenyl surface treated manganese ferrite with acrylic ester polymer (generic);
