The International Agency for Research on Cancer recognizes arsenic and arsenic compounds as Group 1 Carcinogens, and the EU lists arsenic trioxide, arsenic pentoxide
and arsenate salts as Category 1 Carcinogens.
Copper oxide, chromium trioxide, and arsenic pentoxide retention in the flakeboard samples is shown in Table 2.
Figure 1 shows the total copper oxide, chromium trioxide, and arsenic pentoxide retention in CCA-treated guardrail posts from different horizontal positions (outer, middle, and inner) and vertical positions (top, middle, and bottom).
Over 60 drums of arsenic pentoxide were lost overboard from an Ethiopian cargo ship in a North Sea storm last month.
Arsenic pentoxide - used as a wood preservative and in pesticides - is highly toxic if inhaled or eaten and in extreme cases can cause cancer.
More than 60 barrels of arsenic pentoxide are still missing after being lost from the cargo ship Andinet off the Dutch coast before Christmas.
Arsenic pentoxide is very toxic if inhaled or eaten and, in extreme cases, can cause cancer.
CCA is used worldwide for wood preservation, and it contains varying percentages of mixtures of arsenic pentoxide
, chromium trioxide, and cupric oxide.
5%, NaOH 99%, arsenic pentoxide
, and cadmium standard solution (1,000 mg/L) of analytical grade were purchased from VWR Int.
The standard 20 [micro]g/L of arsenic pentoxide
was run two or three times in one lot.
