If you keep asking sensible questions like that you will upset the doomsters

Rape pollen is highly irritating to kids with asthma and it produces lots of it ! It is also a shitty thing to have near you if you have bees as the honey is murder to get out of the frames.

Windguy, The use of municipal sewage has been an ongoing project for a sustainable cities proponents, but my impression is that they keep running into problems with waste that wouldn't be good for the land. Cleaners, chemicals, like pesticides that people flush down the toilette,

I think it is an excellant opportunity for society but we have to be aware of, and prevent, the side effects that might damage crops or the soil itself.

Do the cleaning products that advertise themselves as biodegradable negate this problem?

Bacteria can clean up anything,look at all the recycling of water carried out along the rivers in the UK.Due to the presence of heavy metals some of it may not be potable,but is certainly good for irrigation. Research is ongoing but waste water has been cleaned up for donkies years in Britain and ireland.I think that the US lags behind a bit on this one.

I don’t know where you get your information from sometimes. Children with hay fever can have asthma attacks caused by pollen Allergens & Irritants: Pollen - About Asthma > A - Z Asthma Triggers > Pollen Allergy and Pollen FAQs Asthma UK - Pollen ALLSA - Allergy and Asthma: Part 3: Pollen and Asthma . However, it is only wind born pollen that does it. Canola pollen is heavy and sticky, ideal for movement by bees, but not by wind. Typical plants that cause hay fever are grasses, ragweeds, other members of the daisy family, trees like willows, alders, elms, olives, birches and maples.

So it is illegal to grow canola, which doesn’t cause hay fever, near schools, but grasses and trees, which do, are OK?

Where I live, there is a thriving commercial activity of putting hives around canola fields. I can also buy canola honey in the stores.

A number of cities do use treated sewage for irrigation, including where I live. The main problems are the amount of water and sludge that can be retrieved compared to the need. There have been issues with heavy metals, cadmium, from memory and care needs to be taken with the crop it is applied to.

Is Canola deffinitely the same plant as Oil Seed Rape? Surely Oil Seed Rape must have wind borne pollen if you can smell the fileds really strongly whenever you drive past and the flowers are out? It reeks.

Canola is the same as oilseed rape, but not exactly the same as rape. Canola was invented in Canada and Canola is short for Canadian oilseed (well sort of). The Europeans when they adopted it decided to call it something different.

What you smell is not pollen. It is isothiocyanates. Canola, like most mustards, contains glucosinolates, which are broken down into isothiocyanates when the cells are damaged. Mustard gas, used in WWI, was an isothiocyanate. There is a faint sulfur smell.
