Confused about due date and how many weeks I am. I used the Due date calculator on this site and several other sites and my due date came up as 8 weeks. However when I went for an early scan they dated me as being 6 weeks 5 days, that was on Friday so I would be 7 weeks + 2 today according to the scan. My last period was 12 April and I believe I conceived around 26/27 April. Can anyone explain this please. How many weeks am I and when will the baby be due.
Volcanic eruptions emit water vapor and toxic gases into the atmosphere. Learn about the gases emitted from an erupting volcano, such as carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrochloric acid and carbon monoxide and their effects in this video lesson.f significant amounts of these compounds are emitted from a volcanic eruption, they can irritate eyes and respiratory systems. Carbon monoxide can also be released during a volcanic eruption. Carbon monoxide is a gas you may have heard of as a dangerous gas that can come from a faulty heater or appliance in your home.
Large eruptions can release enormous amounts of gas in a short time. The 1991 eruption of Mt. Pinatubo is thought to have injected more than 250 megatons of gas into the upper atmosphere on a single day. However, even if magma never reaches the surface, gases can often escape continuously into the atmosphere from the soil, volcanic vents, fumaroles, and hydrothermal systems. By far the most abundant volcanic gas is water vapor, which is harmless.
